Description

  The present invention relates to a solar tracking panel, and more particularly, to an automatic correction method for swinging and tilting a solar panel until the entire panel is irradiated with sunlight, and a drive unit, an optical sensor, and a control unit that execute the method.

  Conventionally, a solar tracking type solar panel that automatically swings according to the irradiation angle of sunlight, as disclosed in Patent Document 1, is mainly mounted and driven on the top of a swingable bracket. A unit is installed adjacent to the bracket, and the control unit determines the sunlight irradiation angle based on the season and time, swings the solar panel according to the bracket, and irradiates the light receiving end face of the solar panel. To optimize the angle.

  Further, the conventional solar tracking type panel described above has a technology for generating power simultaneously by using a plurality of sets of solar batteries provided adjacent to each other in Patent Document 2, for example, in addition to generating power by using only one set of solar panels. It is disclosed. In this technique, a connecting rod is mainly pivotally attached to each solar battery, and is swung synchronously in the solar tracking direction by the solar battery.

  With the arrangement described above, when a plurality of solar panels are simultaneously generated and actually used, a plurality of solar panels are connected in series to form one series circuit, and a plurality of solar batteries of the solar panel are connected in series. One circuit is formed. Therefore, when sunlight is irradiated on the entire light receiving end face of the solar panel, power is generated by the solar battery, the series circuit is conducted, and electric power is output to the outside.

  However, when multiple solar panels swing in the direction of solar tracking synchronously, the end that jumps up due to the swing of each solar panel blocks the sunlight that is irradiated to the lower end of the adjacent solar panel, A shaded area is formed on the light-receiving end face of the lower edge of the panel, the solar battery provided in this shaded area stops power generation, the series circuit is disconnected, and power generation of the solar panel is temporarily stopped. If the solar panel is not swung until the entire end face can be irradiated with sunlight, it cannot be activated again to generate power.

  However, with respect to the problem that the above-described solar panel swings to form a shaded area and power generation temporarily stops, the above-described prior art does not disclose a method for effectively preventing the occurrence of the shaded area. Therefore, improvement of this point has been demanded.

  Step S40: Continue to compare potential signals matched by the control unit 4.

  Step S51: The control unit 4 divides the sunshine area into one predetermined time range in which the day illuminance is high and a plurality of predetermined time ranges in which the day illuminance is low. The predetermined time range in which the daily illuminance is high refers to the time in which the solar irradiation intensity is high within the time range of the day. Means a time zone in which the irradiation intensity of the sun within a time range of one day is low, and in this embodiment, includes a time zone in the morning and afternoon. Here, noon is 12:00 noon of Greenwich Mean Time (GMT) at the surface position where the solar panel is attached. The time zone after noon is actually between 10 am and 3 pm as defined by the user. The predetermined time range in which the illuminance is low is the sunshine hours other than the time zone before and after noon and varies depending on the season. For example, on the surface of the ground near the North Return Line, the summer periods are 5am to 10am and 3pm to 7pm. The user can set the user himself / herself according to the actual attachment position, and will be described here by way of example. However, the present invention is not limited to this.

  Step S52: The control unit 4 continues to determine whether or not the current time is within a predetermined time range in which the daily illuminance is high.

  When the current time is between 5:00 am and 10 am in the early morning, and the sun gradually rises from the eastern sky on the surface of the earth, and comes to the eastern sky of the first panel 11, the second panel 12, and the third panel 13. The control unit 4 controls a predetermined angle of sun tracking, and the drive unit 2 swings the first panel 11, the second panel 12, and the third panel 13 in the direction of the sun (see FIG. 6). A predetermined angle α1 for solar tracking is formed between each of the top surfaces of the panels 11, 12, and 13 and the horizontal plane, and the predetermined angle for solar tracking is determined by judging the operating angle of the sun based on the season and time. To do. If the light beam 5 applied to the second panel 12 is blocked by the first panel 11, a dark region 62 is likely to be formed in a part of the light receiving end face 120 of the second panel 12. At the same time, if the control unit 4 determines that the current time is not within a predetermined time range with high daily illuminance, it determines that the current time is within a predetermined time range with low daily illuminance.

  Step S53: When the current time is not within a predetermined time range in which the daily illuminance is high, the control unit 4 compares the potential signals of the first photosensor 31 and the second photosensor 32 with each other.

  When the current time is between 5:00 am and 10:00 am in the early morning, a bright region 61 is formed on the west surface of the shaft 122 by receiving the sunlight 5 (see FIG. 9), so the second photosensor 32. Receives a light beam 5 in a bright area 61 to generate a high potential signal. Since the first optical sensor 31 and the second optical sensor 32 have a creepage distance h1 (see FIG. 8), the creepage distance h1 actually includes the diameter of the shaft 122, the first optical sensor 31, and the second optical sensor 32. The surface width of the optical sensor body 3 connected to the second optical sensor 32 is included. The protrusion 30 formed by the creeping distance h1 can easily block the east surface or the west surface of the shaft 122 irradiated with the sunlight 5. At this time, when the east surface of the shaft 122 irradiated with the sunlight 5 is blocked by the protrusion 30, a dark region 62 is formed, and the first photosensor 31 located in the dark region 62 is irradiated with the light beam 5. If not, a low potential signal is generated, the potential signals of the first photosensor 31 and the second photosensor 32 are different, and a potential difference exists.

  Step S54: When there is a potential difference between the matched electronic signals, the control unit 4 compares the potential signals of the first optical sensor 31 and the second optical sensor 32 with each other.

  When the current time is between 5 am and 10 am in the early morning, the second photosensor 32 generates a high potential signal that is higher than the low potential signal of the first photosensor 31.

  Step S541: The control unit 4 drives the end on the one end side of the light receiving end face 120 provided with the light sensor for generating the low potential signal by the drive unit 2, and rises as the second panel 12 swings. Then, the end on the other end side of the light receiving end face 120 provided with the photosensor for generating a high potential signal is lowered in accordance with the swing of the second panel 12.

  Since the current time is between 5 am and 10 am in the early morning and the potential signal of the second photosensor 32 is higher than the potential signal of the first photosensor 31, the light receiving end face provided with the first photosensor 31 The end 123 on the east end side of 120 is driven by the drive unit 2 and is raised in accordance with the swing of the second panel 12 (see FIGS. 7 and 10), and light reception provided with the second photosensor 32 is provided. The end portion 124 on the west end side of the end surface 120 is driven and lowered in accordance with the swing of the second panel 12, and the second panel 12 is swung in the sun tracking direction. The panel 13 is interlocked and swung in the sun tracking direction. During this period, steps S52, S53, S54, and S541 are repeated. When step S53 is repeated, the second panel 12 is swung to the east and west surfaces of the shaft 122 in the sun tracking direction, and when irradiated with the sunbeam 5, bright areas on the east and west surfaces of the shaft 122 61 are formed, and the first optical sensor 31 and the second optical sensor 32 are irradiated with the sunlight 5 to generate equal potential signals.

  Step S55: When the current time is between 5 am and 10 am in the early morning and the potentials of the potential signals are equal, the drive of the shaft 122 by the drive unit 2 is stopped by the control unit 4, and the first panel 11, second The swinging of the panel 12 and the third panel 13 is stopped, and an actual angle α2 of the sun tracking is formed between each of the top surfaces of the panels 11, 12, 13 and the horizontal plane (see FIGS. 7 and 10). The angle values obtained by subtracting the angles α1 and α2 are inclination compensation values for solar tracking of the panels 11, 12, and 13, respectively. As a result, the dark region 62 on the light receiving end face 120 can be eliminated immediately, and the entire light receiving end face 120 can be irradiated with sunlight to increase the sensitivity of the solar panel swing compensation. During this period, steps S52, S53, and S55 are repeated. Step S53 is repeated, and when there is a potential difference in the potential signal, steps S52, S53, S54, and S541 are repeated.

  Step S52: When the current time is between 10:00 am and 12:00 noon, the sun gradually moves from the west to the eastern sky above the first panel 11, the second panel 12, and the third panel 13 or near the top. In this case, the control unit 4 controls the predetermined angle of sun tracking, and the drive unit 2 drives the first panel 11, the second panel 12, and the third panel 13 to swing in the direction of the sun (see FIG. 11), a predetermined angle α3 for sun tracking is formed between each of the top surfaces of the panels 11, 12, and 13 and the horizontal plane. During this period, when the sunlight 5 irradiated to the second panel 12 is blocked by the first panel 11 and a dark region 62 is formed on a part of the light receiving end face 120 of the second panel 12, the control unit 4, it is determined that the current time is within a predetermined time range with high daily illuminance.

  Step S56: When the current time is within a predetermined time range where the daily illuminance is high, the control unit 4 compares the potential signals of the third and fourth photosensors 33, 33a, 34, 34a with each other. .

  When the current time is between 10:00 am and 12:00 noon, and the end 124 on the west end side of the light receiving end face 120 is irradiated with the sunbeam 5 to form a bright area 61, the sunbeam 5 is formed in the bright area 61. , And the fourth photosensors 34, 34a generate a high potential signal. When the first panel 11 blocks the sunlight 5, a dark region 62 is formed at the end portion 123 and the tip angle 126 on the east end side of the light receiving end surface 120 of the second panel 12, and the third light in the dark region 62 is formed. The sensors 33 and 33a generate a low potential signal when they are not irradiated with the sunlight 5, and the potential signals of the third and fourth photosensors 33, 33a, 34, and 34a are different and a potential difference exists.

  Step S57: When a potential difference exists in the potential signal, the control unit 4 compares the potential signals of the third and fourth photosensors 33, 33a, 34, and 34a with each other. When the current time is between 10:00 am and 12:00 noon, the fourth photosensor 34 generates a high potential signal that is higher than the low potential signal of the third photosensor 33.

  Step S571: The control unit 4 drives the end portion on one end side of the light receiving end face 120 provided with the optical sensor for generating the low potential signal, and raises it with the swinging of the second panel 12, and also increases the high potential. The end on the other end side of the light receiving end face 120 provided with the optical sensor for generating a signal is driven and lowered with the swing of the second panel 12.

  When the current time is between 10:00 am and 12:00 noon, the potential signal of the fourth photosensors 34 and 34a is higher than the potential signal of the third photosensors 33 and 33a. The end portion 123 and the tip angle 126 on the east end side of the light receiving end face 120 provided with the sensors 33 and 33a are driven and raised according to the swing of the second panel 12 (see FIG. 12), and the fourth light The light receiving end face 120 provided with the sensors 34, 34a is driven with the end portion 124 and the tip angle 127 on the west end side, and is lowered in accordance with the swinging of the second panel 12, and the second panel 12 is moved in the sun tracking direction. The first panel 11 and the third panel 13 are swung synchronously in the sun tracking direction.

  During this period, steps S52, S56, S57, and S571 are repeated. When step S56 is repeated, the second panel 12 is irradiated with the sunlight 5 by swinging the east and west end portions 123 and 124 and the tip angles 126 and 127 of the light receiving end surface 120 in the sun tracking direction. The bright regions 61 are formed at the end portions 123 and 124 and the tip angles 126 and 127 on the east and west end sides of the light receiving end surface 120, respectively, and the third and fourth photosensors 33, 33a, 34, and 34a are sunbeams 5 respectively. Are simultaneously generated, the same potential signal is generated.

  Step S58: When the potentials of the electronic signals described above are equal, the control unit 4 stops the shaft 122 driven by the drive unit 2, and the first panel 11, the second panel 12, and the third panel 13 are stopped. Since the swinging is stopped and the actual angle α4 of the sun tracking is formed between each of the top surfaces of the panels 11, 12, 13 and the horizontal plane (see FIG. 12), the dark region 62 on the light receiving end surface 120 is Immediately disappear, the entire light receiving end face 120 is irradiated with sunlight, and steps S52, S56, and S58 are repeated during this period. Step S56 is repeated, and steps S52, S56, S57, and S571 are repeatedly executed when there is a potential difference in the above-described potential signal.

  When step S57 is repeatedly executed, the current time is between 12:00 noon and 3pm, and the sun gradually moves westward above the first panel 11, the second panel 12, and the third panel 13. When operating near the upper west sky, the control unit 4 causes the drive unit 2 to move the first panel 11, the second panel 12, and the third panel 13 toward the sun based on a predetermined angle of sun tracking. A predetermined angle β3 for sun tracking is provided between each of the top surfaces of the panels 11, 12, and 13 and a horizontal plane. During this period, when the end portion 123 and the tip angle 126 on the east end side of the light receiving end face 120 are irradiated with the sunbeam 5, a bright area 61 is formed, and the third photosensors 33 and 33a are sunbeams in the bright area 61. When receiving 5, a high potential signal is generated. At this time, when the sunlight 5 irradiated to the second panel 12 is blocked by the third panel 13, a dark region 62 is formed at the end 124 and the tip angle 127 on the west end side of the light receiving end surface 120, and the dark region When the fourth photosensors 34 and 34a located in 62 do not receive the irradiation of the solar beam 5, the fourth photosensors 34 and 34a generate a low potential signal, and the potential signals of the third photosensors 33 and 33a are the fourth photosensor 34. , 34a becomes higher than the potential signal.

  Step S572: When the drive unit 2 is driven, the control unit 4 raises the end on the one end side of the light receiving end face 120 provided with the photosensor for generating a low potential signal in accordance with the swing of the second panel 12. At the same time, the other end of the light receiving end face 120 provided with the photosensor for generating a high potential signal is lowered in accordance with the swing of the second panel 12.

  When the current time is between 12:00 noon and 3 pm, the potential signal of the third photosensors 33, 33a is higher than the potential signal of the fourth photosensors 34, 34a. The end portion 124 and the tip end angle 127 on the west end side of the light receiving end face 120 provided with the fourth photosensors 34 and 34a are raised according to the swing of the second panel 12 described above (see FIG. 14). The end portion 123 and the tip angle 126 on the east end side of the light receiving end surface 120 provided with the third photosensors 33 and 33a are lowered according to the swing of the second panel 12, and the direction opposite to the sun tracking direction. The second panel 12 is swung, and the first panel 11 and the third panel 13 are swung in the direction opposite to the sun tracking direction. During this period, steps S52, S56, S57, and S572 are repeatedly executed. When step S56 is repeatedly executed, the second panel 12 is swung in a direction opposite to the sun tracking direction, and the third and fourth photosensors 33, 33a, 34, and 34a generate equal electronic signals. , S52, S56, and S58 are repeatedly executed, and the actual angle β4 of the sun tracking is formed between the top surface of each panel 11, 12, and 13 and the horizontal plane (see FIG. 14), and step S56 is repeated. If there is a potential difference in the potential signal, steps S52, S56, S57, and S572 are repeated.

The panel 13 is swung synchronously in the direction opposite to the sun tracking direction. During this period, steps S52, S53, S54, and S542 are repeated. When the same potential signal is generated in the first and second photosensors 31 and 32 when the step S53 is repeatedly executed, the steps S52, S53, and S55 are repeatedly executed, and the top surfaces of the panels 11, 12, and 13 are executed. The actual angle β2 of the sun tracking is formed between each of these and the horizontal plane, and step S53 is repeated, and if there is a potential difference in the potential signal, steps S52, S53, S54, and S642 are repeatedly executed.

By this, sunlight is blocked by the solar panel, and the dark area formed on the light receiving end surface 120 of the adjacent solar panel is immediately eliminated to prevent the power generation of the solar panel from temporarily stopping, Improve solar panel power generation efficiency.

  In addition to this, the present invention compares the potential signals of the third and fourth photosensors 33, 33a, 34, and 34a by the control unit 4 within a predetermined time range in which the daily illuminance is low. If there is a potential difference, the first panel 11, the second panel 12, and the third panel 13 are swung synchronously until the potentials of the potential signals become equal and stop. At the same time, the control unit 4 compares the potential signals of the first and second photosensors 31 and 32 within a predetermined time range in which the daily illuminance is high, and when there is a potential difference between the potential signals, the potential of the potential signal is The first panel 11, the second panel 12, and the third panel 13 are swung synchronously until they are equal.
